This is a specification comparsion between a Nortek Signature 1000 ADCP and a Rowe Technologies Inc. SeaWAVE 1.2MHz ADCP. Both will come with 5 beams. The Nortek ADCP is a 1MHz ADCP. The Rowe Technologies Inc. ADCP is a 1.2Mhz ADCP. This is solely based off the specfications. There are additional features that both ADCPs possess, but this is not included in the comparison.
A Green box mean this option was better.
